stand 1 and has a crank 24 on its end projecting' outside the stand (Figs. 2 and 4).

y turning the crank with the sun (clockthe wheel 2O and all of the rollers 18 and 19 will be brought to rotate against the sun, so that the wires 17 are wound on the rollers, and the bridge will be lowered towards the cylinders 5 and 10, the pistons 6 being driven downwards in the cylinders 5 and pressing the air back into the receiver 2. The wires 17 and the pulleys 15 and 16 thereby act like pulley-tackle exerting additional pressure on the' pistons 6 against the pressure 'of the air contained in the receiver 2, At the same time the piston 11 is pressed down in the cylinder on account of the wheel 14 working on the rack 13 of the piston rod 12, andv air or milk contained beneath the piston 11 ,will be let out through a valve 25 in the piston.

By means of a gearing the wheel acts upon a shaft 26 mounted in the stand 1 and connected with cranks or eccentrics 27, whose journals, by means of links 28, are connected with the pistons 29 in cylinders 30 connected with the teat-cups by means of conduits lBy means of anothergearing` the wheel 2O drives a shaft 31 mounted in the stand and Vprovided witha regulator 32. A screw 34 passing through the stand works upon a brake-dise 33 carried bythe shaft 31 and intended to regulate the speed of the shaft 31 'and consequently the speed of all the moving` parts of the machine, or to interrupt the movements, when forcibly pressed against the brake-disc.

" Those wheels beloning to the two gearings, which are in gear with the toothed wheel 20, are connected with their respective shafts by means of catches so arranged that the first-named wheels, when the machine is being wound up by means of the crank 24, are disconnected from their shafts, but o therwise coupled to them, so that the respective parts (pumps and regulator) are disengaged only when the machine is Wound up.

rlhe cylinder 10 and the pumping means 29,30'are, as above stated, in communication with the test-cups 37. The space beneath the piston 11 in the cylinder 10 is by a conduit 35 and branch pipes 36 in communication with the spaces comprised within the inflators in which the teats are placed during the milking process. A suction valve (not shown) is preferably arranged between the cylinder 10 and the conduit 35.

This conduit opens into a vacuum-meter 38, by which the degree of suction in the teat-cups can be read in order to be regulated by the screw 34 working on the brakedisc 33. The conduit 39 from the cylinders 29, 30 communicated through branch conduits 40 with the spaces outside the intlators in the teat-cups.

A valve (not shown) is arranged at any suitable point (preferably on the pipe 3) for forcing air, or other fluid, into the receiver 2.

The machine works in the following nainner: lt is supposed that the machine, has been run so far that the pistons and 1l in the respective cylinders 5 and 10 have reached their upper final positions, which are determined by the piston 11 strikingagainst the stand 1. lf then the crank 24 is turned round, the wires 17 will he wound upon the rollers 18 and 19, and the pulleys 15, 1G together with the wires 17 act like a pulleytackle bringing down the bridge 8, the pistons G and 11 thus being brought into their initial positions in the cylinders 5 and l() respectively. rlhe air beneath the pistons (l in the cylinders 5 will then be forced through the pipe 3 into the receiver 2, in which the pressure will be raised, and the air beneath the piston 11 in the cylinder 10 escapes through the valve 2F. After the machine has been wound up in this manner, the screw 34 is screwed against the brake-disc 33, so that the different parts of the machine are kept in their initial positions. By slaekenino' the screw 34 a little, the machine is st: The air comprised in the receiver 2 will force the pistons 6 in the cylinders 5, and accordingly the bridge 8, upwards, in consequence whereof the wires 17 are wound oli1 the rollers 1S and 19 (see Figs. 1 and 4). The winding off of the wires from the rollers 18 brings the toothed wheel 14 to rotate, so that the rack 13 will lift the piston 11. The rarefmftion of the air thus taking` place in the space heneath the piston 11 will cause milk to he drawn from the teats through the conduit 35 into the cylinder 10, or into a vessel connected therewith and in which a rarefaction of the air contained therein is also caused by the rising movement of the piston 11. The x 'hiding olf ofthe wire 17 from the rollers 19 brings the toothed wheel 2O to rotate. and to start the pumps 29, 30, so that the teats are subjected to a pulsating pressure giving them the requisite massage, and also to .set the regulator 32 and the brake disc 33 in rotation. The speed of the movable parts of the machine can he regulated by means of the. screw 34, so that the machine can at any time be adapted to varying conditions.

AAfter the cylinder 1() and the vessel (which may be connected therewith) have heen tilted with milk and removed (by unhooking the hooks 9), emptied, and replaced, the machine is again wound up in the aforesaid manner and checked in this position by tightening the screw 34 against the brake-disc 33 and so on.

In second form of construction another arrangement is chosen for moving the ln-idge S, from which power is transmitted to the pistons 6.

A pair of watch-springs 42 are fixed to the shaft 41 mounted in the stand and carrvi the toothed wheel 14, and another pair fi (l llt) tit?

.- shalt 43 mounted in the stand.

watch-springs 44 are lined to a shaft 43 also mounted in the stand. The shafts 41 and 43 carry toothed wheels, 45 and .46 respectively, engaging with a pinion 47 fined to a. short That end ot this shaft which projects out otl the stand, carries a crank 49, by means of which the machine is to be wound up, and during this process the springs 42 and 44 are tightened, and the pistons 5 and 11 are lowered in their cylinders 5 and 10 owing to the wheel 12 working on the rack 13.

On the shaft 43 is fixed a toothed wheel 50 engaging with. a pinion 51 on a shaft 52 mounted in the stand, this shaft carrying a toothed wheel 53 engaging with a pinion 54 carried on a shaft 55 mounted in the stand. This latter shaft carries the cranks or eccentries 27 acting upon the pistons 29.

The shaft 55 acts upon a gearing for drivingthe spindle 31 together with the regulator By meansof a pawl device the toothed wheel 51 is connected with the shaft 52, so that, when the machine is being wound up by means of the crank 49, the toothed wheel 51 is disengaged from its shaft, but otherwise it is coupled to it. A suctionvalve 35 is arranged between the cylinder 10 and the conduit 35.

ln this :term the machine works in the following manner: By turning the crank 49 the springs 42 and 44 are tightened and owing to the toothed wheel engaging with the rack 13 the pistons G and 11 are driven downwards to their initial positions in the cylinders 5 and 10 respectively. The machine is then run in the aforesaid manner. The degree of pres.- sure from the receiver 2 is increased by the pressure ofthe springs 42 and 44, so that pow cr will be transmitted by the toothed wheel 14 to the rack 113 and the rod 12. When the springs distend, the pumping device 29, 30 is set in motion for working on the teat-cups in the aforesaid manner.

lit desired, the machine may be wound up by acting upon the rod 14 by a crank, for instance.

This form of construction presents a special advantage, inasmuch as it can be used equally well for hard-milked and easily milked animals. In the latter case only one of the driving means (springs `or air pressure) but in the former case both of them are to be used. The total amount oit power can be regulated by regulating the pressure from the air and the springs, or either.

Provided the receiver 2 and the cylinders 5 and the conduits connecting these members are prefectly tight, a leakage through which pressure fluid might escape, could only occur round the pistons 6. By a special construction et the pistons (independent of the present invention), such leakage may be practically prevented. lith such a construction of the pistons, the machine is at any time ready to be put to work Without wasting time in pumping in pressure fluid.

From theabove it will be seen that all parts of the machine are positively guided so as to operate regularly together, thus ensuring a satisfactory milking.

The arrangements ot the details and the mode of transmitting motion may vary without departing from the spirit ot the invention.
